Ultrafast symmetry-breaking charge separation in thin films of J-aggregated perylenediimide multimers in a nonpolar solid-state environment
We demonstrate ultrafast symmetry-breaking charge separation (<i>τ</i><sub>CS</sub> <110 fs) in thin films of J-aggregated perylenediimide (PDI) multimers in a nonpolar polymethyl methacrylate polymer matrix (<i>ε</i> = 2.80-3.20). Theoretical calculations reveal the role of through-space electronic communication and π-π interactions promoting ultrafast charge separation in PDI multimers in the solid-state.
